turn isarranged on a base 3, the latter in pivoted to the base at 5, andhaving a main operating bar or member 6 connecting it with the shutterand platen operating mechanism in the upper casing, a" spring 7 .nor-

mally operating to return the treadle to norlocking or detaining device8 beingpreferably provided to hold the treadle in operated position,when desired, this, detaining device in the present instance comprisinga detent pivoted at 9 and having a projection 10 arranged to move intocooperative engagement with a part of the treadle to retain itdepressed, i

The printing mechanism-proper contained in the upper casing comprises,1n the present instance, a substantially closed printing or exposurechamber 11 having an aperture at one end to receive light from asuitable source, while its opposite end is closedby a diaphragm 12,having an aperture 13 therein through which the light rays pass to thenegative and the sensitized material. The negative (see Fig. 7) is heldin operative position by a negative holder comprlsingan mal elevatedposition after each operation, a i

i outer frame 14, supported within the casing by means ofvertically-adjustable screws and 16 and a horizontally-adjustable screw17, the several screws operating on the hearing plates 18 to vary theposition of the negative holder laterally and vertically in a verticalplane. Fitted removably within the outer frame 14 is an inner frame 19,the latter having a beveled edge :20 thereon arranged to enter anundercut groove inthe outer frame to permit their engagement anddisengagement and to n-event lateral disengagement of the two rames whenlocked, the opposite or upper edges of the twov frames being held incooperative relation by a button 21. The inner frame has a form toreceive a negative ag'comprising a relatively fixed angle member 22, thearms of which are arranged preferably at right angles, and acorresponding diagOnalIy adjustable member 23"the latter having inclinedslots 24 therem adapted tocotiperate with the projections 25. Anoperating lever 26 pivoted at 2'1 has a projection 28 resting in anaperture 29 of the movable' member of the form, so that by operatingthis memher, a relative diagonal. movement will be given the membersthat will cause their op-" posing'edges to proximate or move toward oneanother, and when a negative is properly laced in the form it will befirmly clamped 1n position. A spring 26 cooperating with the projection28 serves to normally retain the lever 26 iii-position to secure thenega-' tive.

It is preferable to employ-, in some instances, a vignetter or mask forlimiting the field of exposure so as to provide a border around theprint or for other desired efi'ects, such as tinting, and in 'such casesit is convenient to support the vignetter or other forms indicated at 30on a movable frame 30, the latter for convenience being mounted to swingon a shaft 31 to permit it to be swung into and out of cooperativerelation with the negative, the mask or vignetter being preferablydetachably fastened by impaling it on projections 30 and locking it byswinging the hinged bar 30 behind it, a handle .32 being attached to theframe provided with an aperture arranged to cooperate with theproject-ion 34 on the casing to form a latch for normally retaining thesaid frame in operative position.

The shaft 31 serves to operate the platen or device for holding thesensitized material in printing or exposing position, the platen in thepresent instance embodying a carrier rigidly attached to the operatingshaft 31 and having a rectangular webbed frame 36 at its free end forsupporting the platen proper. In printing sensitized material fromnegatives, it is desirable, in order to obtain the best results, to holdthe sensitized materialvagainst the negative with uniform yieldingpressure, and the platen shown in the presentinstance, comprises aspring-pressed backing '37 supported on 'the front face of the frame 36by means of headed pins 38 which serve as guides for permitting a huntedrelative movementbe-- tween the backing and the frame 36 in'the 'boltf44being arranged behind the plate 40 having key-hole slots thereinarranged to cooperate wlth the heads 42. on the pad to lock the latterto the backing. This enables pads of di-tfei-ent. sizes or forms to beemployed, for, by lifting the bolt 44 the heads 42 are unlocked,permitting the pad to be removed and another of an appropriatesize orform to bsubstitutedZ The pad 43 is provided preferably witha facing offeltor other yielding material so t-hatgth'e sensitized material will bepressed I evenly agalnst the negative, and it issurrounded by rim 43"which f-lS yieldingly pressed forward beyond the impression stir-- face.of the pad by the springs 45 so as to form' a rtweptacle or ledge forsupporting the sensitized material while it is being carried intoengagement-with the negative. To

the back of the platen are pivoted a pair of ejector members 46 and 47having ejector fingers 48 extending through the pad and adapted tooperate beyond the impression sur retracted by means of the lateralextensions 49 thereon resting beneath the springs 45 which serve tooperate the surrounding rim. These ejector members 46 and 47 areprovided with lever arms 50 arranged to cooperate. with thesimultaneously-operable rocker-arms 51 mounted on a rock shaft, 52, thelatter being journalcd in the backing 37 and.-co1nwctcd by a rod to acollar 54, which serves to operate the ejectors. This collar is looselymounted on'a hub provided on acam 56, the latter being fixed by a setscrew or other suitable means to the operating shaft 3], (see Fig. 5)and on the periphery of this collar is formed a projection adapted tocooperate with a shoulder 57 on a spring 58, the cam 56 serving toretract the spring from its engagement with the ejector operating collarat a predetermined point in the movement, of the platen. A

' spring 59 is preferably provided on the rock shaft 52 having a normaltendency to retractthe fingers 51, the latter in turn perace thereof,but. normally they are held son of thep lbport the material until thearm swing sufiicientl far to bring this rim into engagemnt wit thenegative, and the continued movement of the platen carrier 35 will causethe ad 43 to press-the material firmly and eve against the negative, therim 44 yield in a ter engaging the negative, so as to perniitf-theimpression surface ofthe platen to complete'its movement. In cases wherethe vignetter or mask is emplo ed. the ed 'esof the sensitized materialwill e covered y the vignetter or mask so thatthe field or view .w lhave a border of the desired'shape ordesign, the parts being positionedon an aphe material is held in fprinting position for a periodsufiicient to e ect the exposure,

' gropriate frame independently of the platen.

after which,the platen isretracted. However, in the movementof theplaten toward the ne ative, the ejector operating collar is rotatesufficiently to cause the spring to 6peratively enga e the-collantoprevent re-.

verse'movementft ereof, and as the platen "retracted, this, collar willremain st'ationary 'for a period of t-ime sufiicient ito r'ockithe shaft52 and thus tilt the-arms 51 against thelever arms on the ejectormembers,

-.the movement thus impartedt'o theflatter causing theejectorsetS tobe'siinultaneously thrust forward beyond the impression surface of theplaten, operationtof theejector members at the same time {moving the. ex

tensions 49 thereon against'jthe springs 45, causing the rim to beretracted simultane-- ously with the operation of the ejectoi's, theoperations described causing the print'to be removed automatically fromthe/platen.

Continued movement "of the platen will bring the cam 56 intooperative'position, disengaging the spring 58 from-the projection on thecollar 54 and permitting the spring 59 on shaft 52 to draw the fingers51 back from the lever arms 50 on the ejector members, and the latterare operated to re-;

tract the ejectors by the springs 45 operat ing on the extensions 4-9of'the ejector members, and as these ejectors return to normal position,they permit the springs 45 to move the rim forwardly beyond theimpression surface of the platen.

The platen-operating shaft 31 is provided with a crank 60 having a camslot 61 therein adapted to cooperate with a pin 62 carried by the mainoperating member (5, the construction described being such that when therod 6 is depressed, the pm. 62 thereon op-- erating in the cam slot ofthe crank 60, will cause rotation of the operating shaft 31 until itbrings the platen into cooperative relation with the negative, andcontinued motion of the member 6 in the same direction, will cause thepin 62 to operate in a straight por-- tion of the cam slot-61 so that itwill retain the-platen in fixed relation to the negative,

while the-main operating member continues,

to move.

. In exposing photographic materials itis,

preferable to employ a. shutter for cutting oif the light to terminatethe exposure at the right moment, and in the present embodiment' of myinvention I show such a shutter in connection with appropriate mechanismwhereby it may be operated either at the will of the operator, or itsoperation may be timed automatically,. the shutter 63 in the presentinstance being. mounted on a rotatable shaft 64 so that this shutterwill have a swinglngamovement \vithin the printing chamber in order thatit may cover and uncover the exposure opening leading to the-negativeand, the sensitized material. This shaft 64 has a dog 65 fixed theretohaving-a projection 66 ar-- ranged to coo erate with a detent or latch67, the latterli ing a, spring 69 which normally operates to retain thelatch. and the projection on the dog in coiiperative relation to detainthe opeing pivoted at68 and hav eration of the shutter, the opposite endof the latch being provided with areleasing arm 70.' A shutterroperatingmember 71 is pivotally attached to the shutter-operating dog at 72, thelower end of the link having a projection 73 arranged tooperate in alongitudinal slot 74 formed in the main operating member or bar 6, andon this opcrating bar is'provided a latch 75Ywhich; is V pivoted thereonat '76 andhas a spring 77 normally operating tohold a projection, 78 onthe latch. in operative position to engage the projection 73 on theshutter-operating member 71 as the operating bar is depressed, a camsurface 79 being provided on this latch for a purpose that will bepresently.

described. For the purpose of automatirally timing the period duringwhich the shutter remains in exposing position, a suit-- able retardingdevice is provided, which as shown in the present instance, embodies afluid retarded device comprising a cylinder 80 pivoted to the casing at81 and having a piston 82 operating therein which is retarded in itsmovement by the fluid con-- tained within the cylinder, and this pistonis pirotally attached to one end of a rocking lever 83, the latterbeingpivoted at 84 to a pivoted arm 84*, the latter being capable ofbeing set-by .a setting lever 120 to alter. the relation between thereleasing arm 70 of the detent and a projection 83' on the lever 83,this feature serving to alter the pointin the movement of the retardwhere the shutter is released. A latch 85 is pivotally attached at 86 tothe opposite end of lever 83, a shoulder 87 thereon being arranged to beengaged by the projection 73 on the shutter-operating link or member 71as the latter descends, a spring-pressed roller 88 being preferablyemployed for normally the pivot pin the operation of Z n I spring,this-being accomplished in the present, instance. by coiling the springabout a order to vary support 90, and attaching its free end to an arm91 on a rotatable member 92, so that as this member is rotatablyadjusted in dif the effective ferent positions,it will vary force of thespring arm bearing on the projection S0, and operating throughlever'83it .will tend to return the plunger or piston 82 within the cylinder atdifierent speeds. In order that .this springmay be adjusted convenientlyfrom the exterior of the casing, it is preferable to attach an indicator93 to the adjustable member .92

havinga projection 94'tl1e1eon arranged to rest in different recesses 94concentrically arranged on. an index plate 95* which is visiblefrom theexterior of the casing.

In order to set the device for either automatic or manually timedexposures, I provide a setting lever 98 said lever being provided. witha pro ection 97 arranged to cooperate with different notches or recesses99 in 'the said plate to hold the setting lever in adjusted position,the pivot pin 100 on which the said lever I is mounted being extendedthrough the supit to disengage porting plate and provided with an arm100 carrying an inwardly-extending projection 101 arranged to operate ina slot 102 formed in a lever 103, the latter being pivoted at 104: andprovided at its free end with a projection 105 (see Figs. 14 and 15). Byshifting the setting lever 90 to the left, the

rojec-tion 105 of lever.103 will move against the lower portion of thelatch 85, causing from the projection 7 3 on the shutter operatingmember 71, and consequently as the said member is depressed, it willfail to engage the projection 87 on the latch 85, and therefore theretard device will not operate when the shutter is swung whereas by'swinging into. exposing position,

consequently the retard device will be operated at each operation of theshutter.- On. the other hand the pin 101, when the setting lever 96 isin the right hand position, Wlll rest in the path of the cam surface 7 9on the latch 7-5, and as the latter descends to open the shutter, thisprojection will serve .to trip the said latch and the, latch 'throughthe pin 85* from the shutter-operating member (1, leaving the shutterunder the retarding device, closing of the shutter is the control ofHowever, when the; timed manually by the operator, the lever 96 willoccupy the as shown in Fig. 15

left hand position, carrying the projection 101 of the cam surface 79 onthe latch 75, and consequently it will not trip to'release the shutter,so that the shutter will remain open until the operatingbar 6 isreturned to normal or elevated position. vA suitable signal out-of thepath 7 may be employed, if desired, for notifying each closure of theshutter, and this may be forming a projection 106 onv theshutteroperating .inember trip a bell hammer 107 on the spring arm 108as the shutter-operating member operates to close the shutter, so thatthe re eoil of the spring will throw the hammer against a suitable bell109,- a spring 71 connected to the member 71 normally operating to closethe shutter.

provided conveniently by 71' which is arranged to I In order to obtainthe best effects while exposing the photographic material behindunderexposed or thm negatives, it is preferable to employ a series ofsuitably-prepared screens which-may be brought into osition between thematerial and the source of light for the purpose of diffusing, subduingor otherwise modifying the light transmitted to the sensitized material,and a convenient arrangementis shown in the presentembodimcnt of myinvention comprising a frame 110 secured to the front of the casing andhaving a series of grooves 111, 112 and 113 therein in which holders114, 115 and 110 operate, taining the screens which be brought into aposition said holders conare adapted to to intercept thev li ht passinginto the printing chamber,

co rds 117, 118 and 119 passing over suitably-- arranged pulleys andattached to their respective holders} serving to operate them, a mugbeing provided on each cord adapted to be attached to suitableprojections on the exterior of the frame in order that the desiredscreen or screens may be brought into operative posltlon and held by theengage-t ment of the ring with its respective pro ection. In makingprints'or exposures with a de- V100. of the kind described, the sheetsof sensitized material, size, are placed one after another upon thepreferably of the proper a 130 operated rim 43 serving as a su port toprevent the print from droppin rom the platen as it assumes a 'verticaposition. Under normal conditions the shutter is in closed position tocut as the light from the negative which has been previously clampedbetween the relatively-adjustable members 22 and '23 of the negativeholder by move-.

ment of the lever 26, the negative being po- 'sitioned relatively to theplaten by means of the adjustingscrews 15, 16 and 17.. Should it bedesired to make exposures, the duration of which is timed automatically,the setting lever 96-is moved toward the right as indicated in F ig.'14:, thereby hold ing the projection 105 clear of the latch 85,- andbringing the projection 101 into position to trip the latch 75 at theproper moment. By depressin the treadle 4 the main operating bar 6 wille moved from the position shown in Fig. 12 toward the position shown inFig, 11, and this-will first cause the pin 62-operating in the cam slot61 of the crank 60 to rotate the platen-operating shaft 31 to bring theplaten and the sensitized material thereon into coiiperative relationwith the negative, and as the bar 6 continues to move downwardly the pin62 will travel in a strai ht portion of-the cam slot 61 so that the paten will pause or remain motionless, pressing the sensitized materialwith a yieldlng pressure against the rear surface of the negative.However, as this pin enters the straight portion of the cam and at atime when the laten is in engagement with the negative, t e latch 75 onthe bar 6' will reach a point where the projection 78 thereon engagesthe projection 73 on the shutter-operating member 71,- and the continuedmovement ofthe bar 6 will cause the member 71 to-be depressed, rotatingthe dog 65 to which the shutter is attached and bringing the projection66 thereon into latching engagement with the detent 67, the detent thusserving to automatically latch and hold the shutter in open or exposingposition. The downward movement of the shutter-operating member 71 inturn will bring the projection 73 thereon against the projection 87 onthe latch 85, causing the latch to be lowered to set the retardingdevice in operative position. A moment after the-detent has latchingengagement with the sluitter-retaining (log the pin 101 controlled bytlic setting lever 96, will cooperate with the cam surface 79 on thelatch 75 to trip or disengage it and latch 85 from the projection 73 onthe shutter-operating member.

- During the exposure, the treadle 4 is held down either manually or byuse of the detent 8, and the shutter is held open or in exposingposition under-control of the retarding device. As the plunger 82 oftherctardder by the action of the spring 89, the lever 83 will slowlytilt toward normal position,

the arm on the detent at a predetermmed point in the movement of thislever, and continued movementof this lever 83 will disengage the detentfrom the dog, thus allowing the shutter to swing immediately into closedposition and thus terminate the exposure.

In order that the'periods of the exposures may be varied, the pivot 84:for the lever 83 is preferably capable of being shifted, as by mountingit on the pivoted arm 84" and by shifting this pivot to the right orleft by means of the setting lever 120 cooperating with the seriesofnotches 121, the time elapsing between the trip ing of the shutter andthe engagement'of t e pin 83 with the revice, this being accomplished bysetting of the lever 93 I V In some instances 1t is preferable to timethe length of the exposures at the will of the operator, and in suchcases the setting lever 96 is moved into the left hand shown in 'Fig.15, and this wil projection 105 thereon into engagement with the latch85 of the retarddevice, causing it to swing clear of the projection 73on, the shutter-operating member 71. bar 6 is depressed, the platen willbe'swung into coiipcrative relation with the ne ative .by means of thecrank 60, thecam s 0t 61 position, as
